[Issue] To provide a bending instrument for an endoscope with which an extended linking part for joining a fixed part and a sliding part can be easily formed, while the length thereof can be freely set, and a method of producing the same. [Means of Resolution] A fixed part 11 which is attached to the outer periphery of the tip end of an endoscope 15, a sliding part 12 which is slidably attached further towards the base end of the endoscope 15 than the portion where the fixed part 11 is attached, and a linking part 13c for joining the fixed part 11 and the sliding part 12 are moulded as a single piece. A flexible extended linking part 13 is then formed by extending the linking part 13c of the moulded body 10a to a specific length by drawing, and a bending instrument 10 for an endoscope is obtained, which is used to bend the tip end section of the endoscope 15. Furthermore, expanded-width parts 13a, 13b are formed at both ends of the linking part 13c of the moulded body 10a.
